The chassis given by the instructor at the beginning of the quarter is the following:

Wiring Schematic

In order to make the components work as desired, we connected them according to the wire schematic shown below. This includes all the hardware required:

Base Plate

For us to have flexibility when it comes to mounting hardware onto the base plate, we decided to design a plate that had mounting holes all throughout. This plate is mounted on four 2-inch stand-offs from the bottom of the chassis, such that the battery, speed controller and steering servo motor are located underneath the base plate. All other components are located on the top part of the base plate.

CAD of the base plate design

Final product of the base plate

We used a Lasercamm for cutting a 1/4" acryllic

Note: This also shows the Jetson Nano bottom part of the 3D printed shell mounted onto the base plate. The design for the Jetson Nano shell was not design by the team, link to online free CAD is [[1]] . The only change was that we added the side mounts.

The camera shell for the camera was designed so that it would protect the camera, with extended covering from the top part so that the lighting would not affect the image. The camera shell is connected by velcro to an elevated plate that is connected to the base plate by stand-offs. It is important to mention that the angle used for the camera shell design was different for each project of the class. The images below are for the camera mount and shell used on the final project.
